   * JsDiff.diffWords: Word (as defined by \b regex) diff which ignores whitespace
   * JsDiff.diffLines: Line based diff
   *
   * JsDiff.diffCss: Diff targeted at CSS content

  // a transform stream is a readable/writable stream where you do
  // something with the data.  Sometimes it's called a "filter",
  // but that's not a great name for it, since that implies a thing where
  // some bits pass through, and others are simply ignored.  (That would
  // be a valid example of a transform, of course.)
  //
  // While the output is causally related to the input, it's not a
  // necessarily symmetric or synchronous transformation.  For example,
  // a zlib stream might take multiple plain-text writes(), and then
  // emit a single compressed chunk some time in the future.
  //
  // Here's how this works:
  //
  // The Transform stream has all the aspects of the readable and writable
  // stream classes.  When you write(chunk), that calls _write(chunk,cb)
  // internally, and returns false if there's a lot of pending writes
  // buffered up.  When you call read(), that calls _read(n) until
  // there's enough pending readable data buffered up.
  //
  // In a transform stream, the written data is placed in a buffer.  When
  // _read(n) is called, it transforms the queued up data, calling the
  // buffered _write cb's as it consumes chunks.  If consuming a single
  // written chunk would result in multiple output chunks, then the first
  // outputted bit calls the readcb, and subsequent chunks just go into
  // the read buffer, and will cause it to emit 'readable' if necessary.
  //
  // This way, back-pressure is actually determined by the reading side,
  // since _read has to be called to start processing a new chunk.  However,
  // a pathological inflate type of transform can cause excessive buffering
  // here.  For example, imagine a stream where every byte of input is
  // interpreted as an integer from 0-255, and then results in that many
  // bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
  // 1kb of data being output.  In this case, you could write a very small
  // amount of input, and end up with a very large amount of output.  In
  // such a pathological inflating mechanism, there'd be no way to tell
  // the system to stop doing the transform.  A single 4MB write could
  // cause the system to run out of memory.
  //
  // However, even in such a pathological case, only a single written chunk
  // would be consumed, and then the rest would wait (un-transformed) until
  // the results of the previous transformed chunk were consumed.
